As today's consumer electronics and home appliances become more
sophisticated, they require better performance and reliability.
Designers of these types of switch mode power supply (SMPS) systems need
space-saving, cost-effective power supply solutions with high energy
efficiency that meet strict energy regulations. Fairchild
Semiconductor's (NYSE: FCS) FSL1x
series of FPS™ Green Mode Power Switches help designers address
these challenges.

The highly integrated FSL1x series is a two-chip-one-package design with
an avalanche-rugged 650-800V SenseFET and a current-mode pulse width
modulator (PWM) that is specifically designed to reduce component count
and system costs for offline SMPS. Additionally, the green-mode
functionality of the PWM controller helps to meet global energy
regulations by minimizing standby power consumption.

These power switches allow for a longer survival at breakdown mode due
to Fairchild's vertical DMOS technology with rugged avalanche
characteristics, making them superior to the competitor's designs that
utilize lateral DMOS technology. For maximum design flexibility, system
productivity and reliability, the FPS family allows for single platform
design for various input voltage requirements, so that both domestic and
export models can meet all standard passive component requirements.

Compared to other discrete MOSFET and PWM controller solutions, the
FSL1x series provides a basic platform ideally suited for significantly
reducing total system costs and component count without sacrificing
efficiency, productivity and system reliability.

Part of Fairchild's comprehensive portfolio of flyback
power switches that offer first-class performance in fewer
components, the FSL1x series helps designers meet the engineering
challenges they face by providing the technology and process
advancements that result in increased performance and functional
integration in less design time.
